Ingredients
Method
- Whisk together egg yolks, 1/3 cup sugar, 2 tablespoons lemon juice, and 1 teaspoon lemon zest in a small saucepan. Cook over medium heat, stirring constantly, until the mixture thickens. Remove from heat, stir in cubed butter until smooth, and set the lemon curd aside to cool.
- Preheat the oven to 350°F. Grease and flour a 9-inch round cake pan.
- Whisk together flour, 1 1/2 cups sugar, baking powder, and salt in a medium bowl.
- Beat softened butter in a separate bowl until creamy. Add eggs one at a time, then mix in milk, vanilla extract, 1 tablespoon lemon zest, and 1 tablespoon lemon juice.
- Pour the wet ingredients into the dry ingredients and stir until just combined. Pour half of the batter into the prepared pan.
- Spoon dollops of the cooled lemon curd over the batter and swirl gently with a knife. Spread the remaining batter on top.
- Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack.
- Combine blueberries, 2 tablespoons sugar, and water in a small saucepan. Cook over medium heat until the berries release their juices and the mixture thickens. Let the sauce cool slightly before spooning it over the cake.

Notes
Berry Choice:
I have found that frozen blueberries work perfectly for the sauce if fresh ones are out of season: just make sure to simmer them a few minutes longer to cook off the extra moisture.
Curd Technique: When you are swirling the lemon curd into the batter, I recommend using a light hand and only making a few figure-eight motions to ensure you get distinct ribbons of tartness in every bite.
Preparation Tip:
I usually make the lemon curd the night before and store it in the refrigerator: it thickens up beautifully and makes the assembly process much faster when I am ready to bake.
Common Mistake: One lesson I learned early on is to avoid over-mixing the batter once you combine the wet and dry ingredients: stirring just until the flour streaks disappear keeps the crumb light and tender.
